Decompaction of metamorphic rocks under thermodynamic conditions of the Earth crust (experimental data)

Геофизический журнал, 2018
A connection velocity—density inherent to the rocks of deep crust horizons is widely used while plotting concordant model of the Earth lithosphere with the methods of complex interpretation of geophysical data seeking for concordance of rated wave and ...

Melting of subducted sediments reconciles geophysical images of subduction zones

Nature Communications, 2021
Here, the authors identify that magnetotelluric conductive anomalies commonly observed on the trenchward-side of volcanic arcs in subduction zones can be explained by subducted sediments.

Gravity measurement to probe the depth of African-continental crust over a north-south profile: theory and modeling

Heliyon, 2022
Based upon gravity measurements and calculations, the depth of the African continental crust is estimated. Taking as constraints the mass and radius of earth, and measured gravity, this theoretical method explores the use of gravitational potential to ...

Earth’s Earliest Crust

Elements
The scarcity of rocks preserved from the first billion years (Gy) of Earth’s history hinders our ability to study the nature of the earliest crust. Rare >4.0-Gy-old zircons confirm that felsic crust was present within 500 million years of Earth’s formation.

Toward Stable Multivalent Metal Batteries: Understanding the Interfacial Chemistry for Magnesium and Calcium Metal Anodes

Advanced Functional Materials, EarlyView.
Interphase chemistry governs the stability of multivalent metal batteries. We summarize state‐of‐the‐art developments in calcium and magnesium metal batteries by focusing on the correlation among electrolytes, interphase layers, and the electrochemical performance of corresponding metal anodes.

Occurrence State of Rare Earth Elements in the Paleo-Weathering Crust of the Tieling Formation, Northern Hebei Province by X-Ray Diffraction and Electron Probe Microanalysis

Yankuang ceshi
In recent years, the discovered paleo-weathering crustal rare earth ores have the advantages of stability and easy mining. However, due to the low degree of research on their element occurrence state, the study of the enrichment mechanism of the deposits

Studying the Earth with Geoneutrinos [PDF]

, 2013
Geo-neutrinos, electron antineutrinos from natural radioactive decays inside the Earth, bring to the surface unique information about our planet. The new techniques in neutrino detection opened a door into a completely new inter-disciplinary field of ...

Solvent Co‐Intercalation Enabled Ca Storage in MoS2 for Ca‐Ion Batteries

Advanced Functional Materials, EarlyView.
Regulating electrolyte solvation levels enables otherwise non‐intercalatable Ca2+ ions to reversibly co‐intercalate into molybdenum disulfide (MoS2) as ether‐solvated species. The intercalation reversibility is strongly governed by solvent chain length, as demonstrated using diethylene glycol dimethyl ether (G2) and tetraethylene glycol dimethyl ether (

Leaftronics: Bio‐Fractal Scaffolds From Leaf Venation for Low‐Waste Electronics

Advanced Materials, EarlyView.
“Leaftronics” transforms naturally evolved leaf venation into quasi‐fractal scaffolds for sustainable electronics. Polymer‐infiltrated leaf skeletons can be used to fabricate ultra‐smooth, reflow‐ and thin‐film‐compatible decomposable substrates, while making the same lignocellulose networks conducting results in flexible transparent electrodes.
